IMPROVEMENT IN WELL-TUBING.

T0 ALL WHOM IT MAY CONCERN:

Bec` it known that I, 'ANDREW J. EDGETT, of Hornellsville,,Steuben county, and State of New York, (assigner to myself end Jhn W. Ferry,) have invented new and useful improvements in Tube-Wells; and I do hereby declare that the following is a. full und exact description thereof', reference being had to the nceompnnying drawings, making a pait of this specification, in which- Figure 1 is u sectional elevation of my improvements.

Figure 2 is a, transverse section thereof.

Figure 3 is a. vertical section ofthe sume; und

Figure 4 is n transverse section of tig. 3.

The nature of this invention relates to an improvement in tube wells, and consists' in making the driving point in-two parts, one-within the other, each part having openings so nrrangedthnt while the'tube isbeing driven into the ground, the seid openings will be closed, undafter `the tube hns been driven to its proper depth the inner purtconneeting with the-tube may be turned, so es to bring its openings opposite und in linelvith the apertures in the outer part, and thereby allow the witter to enter the tube.

Letters of like name and kind refer to like parts in each ofthe figures.

A represents the outer part or covcringwhich terminates in the driving point A at its lower end, and is open at the to'p to receive'the inner port. B represents the inner part or tube which extends above the top of: the part A, und is provided with u shoulder or clutch, bl, which meshes with a. similar formation on the purt- A, as shown, and screw-shank b3, to'which the well tube is connected. The covering part A hasn number of oblong slots, a, which are mede to be placed in line 'with corresponding openings made in the inner `tnbe B, as shown at b3. The arrangement of the openings a.2` and b3 is such that when the inner tube'B is in the position shown in figs. 1 und 2,'the openings nre closed, und in that position these parts are driven into 'the ground. When the tubeis driven ,to the proper depth, the'tube B (the well-tube being screwed vintov this part) is rst lifted so es to unclutch it with the part A, und. then turned one-quarter 'revolution until the openings of' the pnrtA are opposite the openings in the inner tube B, and then lowered und clutched, thus forming passages for the entrance of the water-into tlieuvcll-tnbe und pump barrel. '.lhis position is represented iii figs. 3 and 4. The shoulder l5 ofthe inner tube has i'our clutch teeth formed upon its under side, which fit into correspond- .ig teethor notches mudo upon the top ofthe part A, :is shown a-t an; by this means the well-tubeis prevented vfrom turning while being driven into thc ground. In order to turn the port B one-quarter revolution, it therefore becomes necessary to first raise it slightly so as to unclutch it from the pert A. A guide-pin, C, projecting inside of the shell into appropriate slots .cut inthe inner tubo B, serves to guide the tube when it is raised and turned within the -part A. It also' prevents the tube B from being -drztwn altogether out of' the part A, und fonms a. proper connection of the v two parts. This improvement is particularly well adapted forV tube wells, inasmuch as it prevents any sand or gravel from entering the tube while it is being driven into the ground. y

My improvement may be attached to any driving pipe now in common use, und while the tube is driven into the ground no sund or gravel willentcr the barrel during the operation. After the required depth has been reached the pump barrel isdslightly lifted and turned one-quarter revolution to thc right, und the writer will enter the barrelthrough the openings a2 and b", as before described.

What I claim us my invention, and desire to secure byl Letters Patent, is

A driving-point for tube wells, composed of two parts, A und B, having openings diend b, screw-shank Il, und each having n clxtch formation, b1, ull arranged und operating in the manner substantially as herein described.
